Thanks for the feedback.

That's our hope, but obviously I can't promise anything :)  But yes,
that's one big reason to think of Tornado, so that we can at least
have basic auth/ssl support for the web entry point.  The kernels by
default only listen on localhost, so it's not that bad: you have a
problem with being open to other local users, but not to the whole
internet.  But since the webnb effectively forwards the
obscure/multiport/local zmq connections over nice, clean,
everybody-understands-it http, it all of a sudden turns an improbable
problem into a likely catastrophe.

Let's see how the next few weeks go, and all help on this front will
be very welcome.

Cheers,
